Audio 50/COMAND APS - Theft Protection Active Displayed

2010 Mercedes Benz Truck GL 350 BLUETEC (164.825) V6-3.0L DSL Turbo (642.820)
Vehicle: All Technical Service Bulletins
Audio 50/COMAND APS - Theft Protection Active Displayed
Audio 50 APS / COMAND APS: The display shows the message "Theft protection active", as a result initial startup not possible/cannot be
completed
Topic number LI82.85-P-049066
Version 2
Design group 82.85 Navigation and communication systems (CNS,
ICS, COMAND, FleetBoard)
Date 05-09-2012
Validity Models 169, 245, 171, 230, 211, 219, 203 CLC, 164 and 251 with COMAND (code 512 or 527) or Audio 50 APS (code 511 or Model 463 with COMAND (code ET4) NTG2.5
Reason for change Removed note to fax CAN log
Complaint:
Fault profile 1/2: The display of the COMAND unit (A40/3) or Audio 50 APS (A2/56) shows the message "Theft protection active".
Fault profile 3/4/5: Initial startup of the COMAND unit (A40/3) or Audio 50 APS (A2/56) cannot be performed with DAS/Xentry Diagnostics or is
aborted prematurely.
Cause:
Re. 1. The COMAND (A40/3) or Audio 50 APS (A2/56) is in the "as-delivered state". In DAS/Xentry Diagnostics go to Actual values/Theft
protection and check the status of the COMAND (A40/3) or Audio 50 APS (A2/56). Initial startup of the COMAND (A40/3) or Audio 50 APS
(A2/56) with DAS/Xentry Diagnostics was not performed during the last installation. The PIN is still stored in the COMAND (A40/3) or Audio 50
APS (A2/56). The COMAND (A40/3) or Audio 50 APS (A2/56) locks after approx. 50 activation sequences.
Re. 2. The COMAND (A40/3) or Audio 50 APS (A2/56) is in the "as-delivered state". Initial startup was performed approx. 2-4 weeks ago and the
PIN has already been redocumented in VeDoc. However, the initial startup was not completed properly due to a procedural error in DAS/Xentry
Diagnostics.
Re. 3. The COMAND (A40/3) or Audio 50 APS (A2/56) is in the "as-delivered state" and is new from the warehouse. Initial startup cannot be
performed with DAS/Xentry Diagnostics because the PIN cannot be read from the COMAND (A40/3) or Audio 50 APS (A2/56). During initial
startup, the PIN was erased with DAS/Xentry Diagnostics too early to allow initial startup to be completed successfully.
Re. 4. In model series 164 and 251 the EZS/EIS control unit (N73) A164 545 15 08 or A164 545 16 08 is installed. The EZS/EIS control unit (N73)
and the COMAND (A40/3) or Audio 50 APS (A2/56) are not compatible with the "Theft protection" function.
Re. 5. The COMAND (A40/3) or Audio 50 APS (A2/56) is in the "CAN signal disrupted" state. The fault code DA00 is stored in the fault memory
of the COMAND (A40/3) or Audio 50 APS (A2/56). Initial startup is not possible because there is a CAN fault. CAN communication to the
EZS/EIS control unit (N73) is disrupted or faulty.
Remedy:
Use at least DAS/Xentry Diagnostics version 11/09 with add-on 1352 or DAS/Xentry Diagnostics version 01/10 with add-on 1354!
Re. 1. Perform initial startup of the COMAND (A40/3) or Audio 50 APS (A2/56) with DAS/Xentry Diagnostics.
Re. 2. Perform another initial startup of the COMAND (A40/3) or Audio 50 APS (A2/56) with DAS/Xentry Diagnostics.
Re. 3. Report the case to your market coordinator with a control unit log of the telematics control unit. He will forward the case to Daimler AG
headquarters. They may be able to determine the PIN again. When the PIN has been determined, perform initial startup of the COMAND (A40/3) or
Audio 50 APS (A2/56) with DAS/Xentry Diagnostics.
Re. 4. Replace the EIS (N73). To do this, determine the part number in the EPC system. Perform initial startup of the EIS (N73) and transfer the
chassis number to the EIS (N73). Be sure to use the correct upper and lower case letters. Perform another initial startup of the COMAND (A40/3) or
Audio 50 APS (A2/56) with DAS/Xentry Diagnostics.
Re. 5.a:
Check whether the chassis number has been transferred correctly in the EIS (N73).
2010 Mercedes Benz Truck GL 350 BLUETEC (164.825) V6-3.0L DSL Turbo (642.820)
1. Use DAS/Xentry Diagnostics to access the menu "EZS/EIS /Control unit adaptations / Write VIN" and check that the chassis number is
written correctly (including upper and lower case letters).
2. Perform a "MOST ring restart" in the COMAND (A40/3) or Audio 50 APS (A2/56) with DAS/Xentry Diagnostics. The menu item
"Restart optical ring" can be found in DAS/Xentry Diagnostics under Audio, Video, Navigation and Telematics.
3. Erase the stored fault in the Audio 50 APS (A2/56) and COMAND (A40/3).
4. Perform initial startup of the COMAND (A40/3) or Audio 50 APS (A2/56) with DAS/Xentry Diagnostics.
Re. 5.b
b: Check whether CAN communication is functioning correctly at the COMAND (A40/3) or Audio 50 APS (A2/56). Perform a quick test
to check other control units for CAN faults and process these faults completely. Then perform initial startup of the COMAND (A40/3)
or Audio 50 APS (A2/56) with DAS/Xentry Diagnostics.
Re. 5.c:
If there are no other CAN faults stored in other control units and the EZS/EIS control unit (N73) contains the correct chassis number,
but the fault code DA00 is still stored and current in the COMAND (A40/3) or Audio 50 APS (A2/56), please log the CAN-B as
described in the attachment. Create a PTSS case and attach the CAN-B log.
Note:
When an Audio 50 APS (A2/56) or COMAND APS (A40/3) with PIN theft protection is installed in a vehicle, the PIN code is
automatically redocumented in the VeDoc system (online) as of DAS version 11/09. After successful initial startup, please check whether
the PIN has been redocumented correctly in the VeDoc system.

He said/She said: 2016 Mazda CX-3 CUV Review

By: Dan Heyman & Lacey Elliot When I was asked to take the 2016 Mazda CX-3 for a spin, I found myself surprisingly excited considering that this type of a car—small/compact crossover—isn’t usually my cup of tea; as a certified auto journalist, and thus, somewhat unbalanced, I’m a big station wagon and hatchback kind of guy. I’ve always felt they provided all the creature comforts of an SUV or CUV, while still providing an engaging ride. However, the CX-3 is a Mazda, and Mazda has to be respected for always finding a way to add that certain je ne sais quoi that makes a car fun to drive and behold, whether that has to do with some funky styling, a firm chassis or engaging powertrain. That’s what happens when you’re known for continually building one of the world’s most exciting, fun-to-drive and above all, affordable, sports cars on the market: the MX-5. Styling So, with that in mind, I sauntered up to our CX-3 tester, finished in brilliant Soul Red metallic paint, and took it in. T...

Product Review: MyZone® Heart Rate Monitor

Today I’m writing up my review of the MyZone® HR monitor! I’ve been using mine now since May and have tested over a range of activities, so now I really believe I can give y'all a fair and informative review. Now, let’s start with the basics. I have the MyZone® MZ-3 physical activity belt, which retails for £129.99 – which, for a heart rate monitor, is fairly pricey considering you can get something like a Wahoo TICKR belt for ~£65 . Purchasing through a MyZone® representative is generally the best way: these tend to be personal trainers or gyms affiliated with the brand. For example, where I live you can get a belt through Henley Fitness Space and save something like ~10% off the RRP. Comfort wise it took a bit of adjusting for me to get used to the belt, but once I found the right position (which for me was just underneath my sports bra) I actually barely noticed the belt was there – which surprised me considering how bulky the monitor is. I find that in this position it sits jus...

Product Review: Garmin Vivoactive 3

So. It’s now been a few months since I’ve had the Garmin Vivoactive 3 and I now think I’ve taken it for enough of a spin to make my full and honest opinion. In short, I very much enjoy the watch and it’s a great training tool but still certainly has its downfalls. The Garmin Vivoactive 3 is a multisport watch with built in wrist HRM, and as with all wrist based HRM that’s were it tends to fall flat. I use my watch primarily to track my rowing, however I’ve also tested it on runs, cycles, swims, ergs, indoor cycles and weights so I’ve tried it all (except golf…). I think the best way to break down my review is to split it into the sports, so I’ll start with the main one for me: rowing. Rowing On the erg I split between either using the ErgIQ app which I downloaded, or just the ‘indoor rowing’ application already on the watch. Out of these I find the ErgIQ gives me the best data, though the concept2 PM5 set up at Leander seems to be slightly temperamental with whether they’ll pick the wa...

Mercedes-Benz ML63 AMG Reliability - 2018 Ratings

New AMG SUV is the first full-size SUV which has that two way of building combined. 2 separate 1/4 mile records were made by two separate RENNtech cars at Palm Beach International Raceway on Wednesday night. The C350 took everything up a notch, but again not a night and day experience, while the C63 is otherworldly, its power devastating, adhesion and correlating road manners unfathomable for such a solid, substantial four-door sedan. I took my girlfriend to an Italian restaurant in Austin, Texas that we had both wanted to try for a while. While the show car does not look anything like the current Impreza, equally Subaru insists the concept鈥檚 styling forms only a guide to the production WRX. The interior of this car has been designed to have an elegant yet sporty look that matches perfectly with the vehicle鈥檚 overall appeal. To get the power onto the road, the rear tires are wider than the front ones on a mid-engined car - usually about 30% wider. Also look for a return of the hybrid S...

We Rank The 5 Audi RS Cars Sold In The US From Worst To Best

Amazingly, only six RS cars have even been sold in the US. RS is to Audi as AMG is to Mercedes and M is to BMW. Even though BMW and Mercedes are quickly expanding their performance portfolios in the US, Audi has lagged behind in offering RS cars in North America. In fact, there was a time when Audi only sold one RS model at a time. This means that (excluding generational overlap) there have only been six different RS models on sale in the US. With only six cars to choose from, we decided to rank the five best RS cars that have ever been sold in the US from so-called "worst" to best. Coming it at number five (the lowest spot) is the RS5. We decided to put the B8 and B9 generation RS5 on this list because neither is our favorite RS car. The RS5 had a few issues. For instance, the engine was out passed the front axel line, which caused understeer. The first RS5 had a naturally aspirated 4.2-liter V8 , which sounded great, but the new car uses a 2.9-liter twin-turbo V6 which a...

2018 Mercedes-Benz AMG C 63 Expert Reviews, Specs And Photos

Under its rear hatch lies a two-cylinder diesel that generates 47 hp, which would have been fairly weak in 1960, much less in the era where the average Hyundai generates up to 200 hp. The new rear fenders make the AMG GT C a total of 2.25 inches wider than the AMG GT and AMG GT S, giving it exactly the same dimension as the AMG GT R at the rear of the car. These are the same rubbers that Nissan used during their 鈥榠nfamous鈥?fast lap of 7mins 29secs at Nurburgring, a timing which was controversially disputed by Porsche recently. 2017 Porsche 991.2 Carrera GTS Photos Redesign for USA, Canada, UK.
